Frank, Didn't know the best octane was 91 in Calif. Guess if I ever make a trip
there I had better carry a few gas cans of 93. We have 93 all over Houston but
sometimes when I get out in the country there is only 92 and the Indy doesn't
like it at all. Our boost is about the same at 4,000 RPM but I usually shift at
5500 (when racing) and the boost is about 8-9 PSI. Don't know what I was
thinking when I told you about my ign. curve. It's set like yours, ie: 93 octane
= 2 deg./lb of boost and 100 octane = 1 deg./lb of boost). was at the track last
night and was talking to a guy who's playing with an alcohol injection system
with the Vortech to cool the charge to the engine.
Ran pretty good. Suppose to talk to him later this week.
I agree, the engine IS very sensitive to fuel.
